I have been running the 2ft SOLARIS on my 29G tank for 10 days now. I yanked out a 250W 10K metal halide, and put this light in its place.
Visually, the tank looks a lot dimmer.. but that also has a lot to do with the fact that the light is a lot bluer than what I am used to or like.
Before putting this light, the tank temperatures ran from 77 to 83-84 degs. After using this light, I have noticed that tank temperature has not gone over 78 degs. Really a big difference as far as heat into the tank is concerned. Some of it can also be due to the fact that now I also have a open tank vs a closed hood before. But clearly, there is very little if any heat comming out of the lamp side of the fixture.
The corals seem to have adapted to the change, and so far I have not seen any ill effects. The tank primarily has soft corals with some LPS like frogspawn, open brain, caulastrea and echinophyillia. They all seem like they are doing fine so far. Its just me who can't still get adjusted to the blueish look of the tank

There is definately move visible flourescence due to the blue LEDs.. this flourescence was masked with the 10K metal halide.
I'll keep you posted on any long term effects I see.
I find it amusing to reed some of the arguments... clearly there are 2 sets of people the Early Adopters and the Majority. Here are recognized differences between the 2 groups. I don't spend my time trying to convince either group
Early Adopters:
Favor revolutionary change
Visionary
Project oriented
Risk takers
Willing to experiment
Generally self sufficient
Early Majority
Favor evolutionary change
Pragmatic
Process oriented
Risk averse
Want proven applications
May need sufficient support
